How to configure Netflow in a Cisco Catalyst 3750

Unanswered Question


I configure netflow in a Cisco Catalyst 3750, but it doesn?t work.

The commands that I had used, are:

ip flow-export source Vlan52

ip flow-export version 5

ip flow-export destination 9996

interface vlan52

ip flow ingress

What else have I to configure?.

Thank you very much.

Best Regards.


I have this problem too.

I have the same problem with Cat3750.

In seems to me that "ip flow ingress" and "ip route-cache flow" commands don't work on it.

Can someone answer the question:

Cat3750 support netflow or not?

Cisco doesn't support netflow on 3550 or 3750 boxes. You may configure it, but no flows are exported. In older IOSes some flows were exported, but it was only 1st packet of the flow. In the new IOSes no flows are exported...
